There is an immediate opening for a motivated postdoctoral fellow to work in the laboratory of Dr. Nancy Ratner. We are looking for a PhD or MD/PhD to generate mouse models and cell lines that contain cells with Nf1 mutations plus variants in identified genes, to test if specific variants are modifiers of nerve tumor phenotypes. Strong candidates must be enthusiastic about working as part of a team of geneticists, statisticians, and rare disease experts to ensure variant selection and project completion. Expertise in molecular biology and neuroscience preferred.
